Corrosion testing.
Our own calibrated salt-spray chamber, to ASTM B117 and NBR 8094. Some of the figures on the site come from an external laboratory or from the technology manufacturer — and the report always says which route it took.
What we have in house.
Salt-spray chamber
Our own calibrated chamber, to ASTM B117 and NBR 8094, up to white or red rust.
Preece test
Checks continuity and thickness of a zinc layer by immersion in copper sulfate.
Kesternich
Sulfur-dioxide atmosphere test — an aggressive industrial condition.
Hull cell
With rectifier and automatic timer, to determine the electrolyte efficiency factor.
Analytical balance
The basis of all gravimetric bath analysis.
Magnetic thickness gauge
A reading that complements the XRF on ferrous substrate.
Sapucaia operates its own calibrated salt-spray chamber, to ASTM B117 and NBR 8094. Part of the published figures comes from an independent external laboratory or from the technology manufacturer — and each one states which, on its own table row.
